Hi Guys, I am looking for a simple, standalone continuity tester. Must have a loud buzzer, lol. It should report a close connection when the total resistance is below 1 ohm, would be great if that can be adjusted. It should also use very small currents for the test, don't want to break any potentially still connected components. I did a google search and didn't see anything ... Yes, I have several multi meters that can do that, but they are typically occupied doing some more serious work, and most of the I can't hear the efing buzzer ... Any pointers, suggestion? Many Thanks, luudee |

I am assuming you mean Continuity Tester Martindale, * TEK402 * Probe voltage: 9V DC approx * Test current: 5mA * Continuity range (audible): up to 10k: nominal * Audible output level: 85dB minimum at 30cm with leads shorted * Overvoltage protection fuse rating: 50mA, 250V, Fast Acting Ceramic Fuse, * TEK404 * Probe voltage: 9V DC approx. * Test current: <50μA (across short circuit) * Continuity range: 0: to 2.2k: ± 10% * Audible output level: 85dB minimum at 30cm with leads shorted * LED indication: bright orange LED Buzzer and LED intensity reduce with increasing continuity resistance |

I did mean "Continuity Tester", thank you for pointing that out ! (I fixed that now in my post) And thank you for those suggestions ! luudee |
